An optimized synthetic route for the preparation of the versatile chiral building block 1,4-di-O-benzylthreitol
摘要:
An improved five-step procedure has been applied to synthesize enantiopure l- and d-1,4-di-O-benzylthreitol out of readily available l- and d-tartaric acid. Through the use of modern reagents and enhanced work-up conditions these useful auxiliaries were obtained in quite perfect yields. In addition, accurate H-1 and C-13 NMR resonance assignments of all synthesized compounds were performed by 2D NMR spectroscopy.
